| 中文摘要 | surface-tethered oppositely charged weak polyelectrolyte block copolymer brushes composed of poly(2-vinyl pyridine) (p2vp) and poly(acrylic acid) (paa) were grown from the si wafer by atom-transfer radical polymerization. the p2vp-b-paa brushes were prepared through hydrolysis of the second ptba block to the corresponding acrylic acid. the p2vp-b-paa brushes with different paa block length were obtained. the p2vp-b-paa brushes revealed a unique reversible wetting behavior with ph. the difference between the solubility parameters for p2vp and paa, the changes of surface chemical composition and surface roughness, and the reversible wetting behavior illustrated that the surface rearrangement occurred during treatment of the p2vp-b-paa brushes by aqueous solution with different ph value. the reversible properties of the p2vp-b-paa brushes can be used to regulate the adsorption of the sulfonated ps nanoparticles. |
